CHARLES GALLE, OF COLUMBIA, MISSOURI.

CUTTING APPARATUS FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 319,222, dated June 2, 1885.

Application filed August 4, 1884.

To aZZ whom it may concern:

Be it known that I, CHARLES GALLE, a citizen of the United States, residing at Columbia, in the county of Boone and State of Missouri, have invented certain new and useful Improvements in Cutting Apparatus for Harvesters, of which the following is a description Figure 1 represents an end view of my improved cutter-bar and the track in which it works. Fig. 2 is a detail plan view of one of the sickles on the sickle-bar. Fig. 3 is a side elevation of the same.

My invention consists in the detailed construction of cutter-bars for harvesters, as hereinafter described, whereby their durability and strength are materially increased, and the cost of construction at the same time diminished, while the sickles may be easily and quickly removed from the sickle-bar for grinding when blunted by use, or replaced when broken. I prefer to form the sickle-bar rectangular in cross-section, and upon this I slide the sickles, which consist of blades with box ends adapted to fit the sickle-bar, and be held upon it by a nut screwed upon the end of said sickle-bar, which is reduced and screwthreaded. The not is kept from turning round and working oil by a plate fastened in the track in which the cutter-bar works.

I will now proceed to describe my inven' tion with reference to the accompanying drawings, in which similar letters of reference, where used in the different figures, indicate corresponding parts.

A is the sickle-bar upon which the sickles B are slid. The sickles B each consist of the blade I), with a solid box end I), which may be constructed by bending a piece of steel to form the blade I) and three sides of the box portion and welding the fourth side on where indicated by the dotted lines; or the sickle may be cast in one piece of substantially the same form, and retaining the flange 19 which forms the sickle-guide. The sickles are kept in position on the sickle-bar by pressing against the sickle head or eye a at one end of it, and at the other end by the nut O. This nut is made rectangular and of the same size outside as the box end of the sickle. It is screwed upon the reduced screw-threaded end a, of the sicklebar A, and draws up tight all (No model.)

the sickles on the bar. The sickles have a reciprocating motion in slots formed in the fingers D, and are guided by the flange N, which slides betweenthe connecting-plates E and F, which hold the fingers apart at a suitable distance. The plate F has a flange, f, which extends lengthwise with the sickle-bar through all that portion of its travel which the nut O traverses, and prevents said nut from turning round and Working off the end of the sickle-bar by the vibration of the ma chine when in operation. Bolts G are passed through parts D, F, g, and E, and secure such parts together,so they can be conveniently detached for repairs or other desired purposes.

It will be seen that any number of the sickles can be removed from the sickle-bar, when required, by unscrewing the nut and sliding them off, and that they can be ground separately. The sickle-bar is not weakened by rivet-holes, as when the sickles are riveted onto it, as commonly constructed, and the necessity of using a specially constructed grinding-machine is done away with.

Having thus described my invention, what I c1aim,and desire to secure by Letters Patent, 1s-

1. The combination, with the finger-bar,the sickle-bar, the blades having boxes fitted on said bar, and the retaining-nut turned on the sickle-bar, of the wear and lock plate F, removably held to the finger-bar, and having a wing, f, depending alongside of and locking the retaining-nut on the sickle-bar, substantially as set forth.

2. Ina cutting apparatus, the combination of the finger-bar, the sickle-bar, the sickleblades having boxes fitted on said bar and provided with rearwardly-projecting flanges h a nut on the sickle-bar, the wear-plate F, having a depending wing fitted alongside of and locking the nut on the sickle-bar, the dis tanee-bar g,placed on the fingerbar, the guideplate E, placed on the distancebar and projected over the flange b of the sickle-blade, and a fastening-bolt, G, substantially as set forth.
